2nd couple is alphax beta
Oo if you mean searching for alpha x beta on here then,
You can click on any manga, scroll down a little under “Comments” should say “Top tags” you can click on any tag and it will take you to a screen where you can search them up !!
If that’s not what you meant then just ignore this loll <3
Im.rlly yearning for some alpha x beta stuff.. does anyone have any recs? I read novels too idk how to search for it too
